' Application filed October 15, 1883 (No model.)

To all whom it may concern Be it known that I, ROBERT S. CARR, of

Hamilton, Butler county, Ohio, have invented certain new and usefulImprovements in Cups for Seeding-llfachines, of which the following is aspecification.

This invention pertains to the force-feed cups used in connection withseeding machines; and it relates to such construction of the cup as topermit the passage from it of all the seed when the cups are to becleaned, in order to change the seed or store the machine.

The invention further relates to such construction of the cups, inconnection with the I 5 mouthpiece of the attached pivotedseed-conductor, that said mouth-piece, while free to oscillate upon itspivot, is not liable to become accidentally detached from the cup.

The nature of the invention will be clearly 2o understood from thefollowing description, taken in connection with the accompanyingdrawings, in which- Figure 1 is a side View of theseed-cup embodying myimprovements; Fig. 2, a vertical section of the same; and- Fig. 3,abottom view of the same, the mouthpiece of the seed-conductor beingdetached.

In the drawings, A represents a scedcup of substantially the usual form,arranged to be secured,along with a series of similar ones,-to

the bottom of the grain-box of the seedingmachine; 13, the side-walls ofthe cup; 0, holes through the side walls for the driving-shaftof thecups; D, the aperture in the side walls,

5 through which slides the grain-gate; E, the

outflow-point of the cup; F, the mouth-piece, adapted to serve the usualflexible seed-conductor; G, the supportingpivots of the mouthpiece, andH the slot in the side walls of the cup, for receiving the pivots of themouthpiece. The parts referred to are all constructed substantially asusual in the general run of force-feed seed-cups, and their general.relation to the present invention is such as to permit in them all .ofthe modifications and variations of structure usual in this generalclass of seed-cups.

Continuing the reference to drawings, I is a sliding gate in the bottomof the seed-cup, fitted to move freely in guides in the side walls,

and to serve, when withdrawn to the rear, to

open freely the extreme bottom of the seedcup; J, the rear wall of themouth-piece and K a latch projecting downward from thefront end of thegate int-o the mouth-piece in front of the rear wall, J.

The seed-wheel and the grain-gates are no shown, as they form no part ofthe present invention, and do not require any speclal modification fromthe usual forms in connection with it.

Force-feed seed-cups are arranged to provide a body of grain below thebottom of the seed-wheel, a function of said wheel being to affect thetop of this body of grain, and carry the grain forward and lift it overan outflowlip of some character. One of the conse quences of thispeculiarity of force-feed seed cups is that with an empty seed-box theseedcups are incapable of entirely emptying the1n- 7'0 selves, a smallbody of grain always remaining unaffected in the shallow chamber belowthe seed-wheel. In changing the characterof grain to be planted, it isdesirable to thoroughly clean the seed-cups, in order that the 7 body ofgrain below the seed-wheels may consist entirely of the new grain. Instoring the machine at the close of the seeding season it is alwaysdesirable that the cups contain no seed or other matter to foul theparts.

In my present invention all the grain will discharge from the seed-cupby opening the bottom gate, I, which is done by pulling it rearward.This gate offers ready facilities for emptying the seed-box of smalllots of grain 85 in case the character of grain is to be'changed or themachine to be stored. The bottom gate,I,is arranged at an inclination,as clearly shown, and'its opening motion is therefore a rising one.Bythis arrangement thetendency 0 of the gate is to remain closed.

The mouth-piece F of the seed-conductor is hooked upon the nose of theseed-cup in the usual manner, and is removed in the usual manner bycarrying it upward and forward until 9 5 its pivots leave theirsupporting-slots.

In the operation of seeding-machines, the raising and lowering of thedrill-teeth has a tendency, through the medium of the conductors whichreach into them, to accidentally untoo hook the mouthpieces, and allowthem, with their attached conductors, to fall. In my construction thelatch-piece K, on the front end of the bottom gate, prevents the usualdisengagement, be it accidental or intentional, of the mouth-piece. Themouth-piece, hanging in its normal position, cannot be carried forwardsufficiently to disengage the pivots from their slots, being preventedby the rear wall of the mouth-piece coming into contact with thelatch-piece of the gate. If, however, the lower portion of themouth-piece be swung forward, its rear wall will then pass under thelatch-piece of the gate, and the desired disengagementis easilyeffected. By this means the accidental disengagement of the mouthpieceis prevented without at all interfering with its ready disengagement,when desired.

The bottom gate not only serves as a lock for the mouth-piece, but themouth-piece also serves as a lock for the bottom gate. It will readilybe seen that the latch-piece K prevents the bottom gate being openedwhile the mouthpiece occupies its normal position. By swinging thebottom of the mouth-piece forward, as previously mentioned, the gate isat liberty to be opened.

I claim as my invention- 1. In a force-feed seed-cup arranged to carry abody of grain below the seed-wheel, and having an opening in its bottom,the combination of side walls of the cup, provided with grooves at thebottom, and a bottom gate fitted to slide in said grooves and close theopening in the bottom of the cup, substantially as and for the purposeset forth.

2. The combination of a seedcup provided with open slots for supportingthe pivoted mouthpiece, hung by pivots to the seed-cup, and a slidingpiece fitted to the bottom of the seed-cup, and having a latch-pieceprojecting into the mouth-piece to prevent the accidental disengagementof the month-piece, substantially as set forth. 7

3. In a seed-cup arranged to carry a body of grain below the seed-wheel,the combination of a bottom opening for draining the cup, a mouth-piecehung to the nose of the cup, and a sliding gate at said opening providedwith a latch-piece projecting downward into the mouth-piece,substantially as and for the purpose set forth.
